Has an AFL game ever ended 98-36?
Exactly once. On August 29, 1953, Sydney beat St Kilda 98-36, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 98-36 in league history.
That makes 98-36 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 99-36 has happened 1 times and 98-37 has happened never.
